Composition visual without framework sample

This sample provides an introduction to the Windows.UI.Composition namespace.

Windows 10 introduces a unified compositor and rendering engine for universal applications. Application can use the Windows.UI.Composition namespace to create composition objects and apply animation, effects and manipulations on those objects.

The sample demonstrates the following:

  • Relying entirely on composition objects, rather than using XAML, HTML, or DirectX.
  • Setting up a Compositor for creating composition objects.
  • Creating a ContainerVisual to hold all of the composition objects.
  • Constructing and walking a simple tree of Visual objects.
  • Using a SolidColorVisual
  • Receiving input and changing opacity of a Visual based on that input.

Note The Universal Windows app samples require Visual Studio 2015 to build and Windows 10 to execute. (See additional discussion below under Prerequisites.)

To obtain information about Windows 10 development, go to the Windows Dev Center.

To obtain information about Microsoft Visual Studio 2015 and the tools for developing Windows apps, go to Visual Studio 2015.

Prerequisites

  • This sample will not pass WACK because it uses the previewUiComposition capability in order to access the Windows.UI.Composition preview namespace.
  • This sample requires Windows 10 build 10240 to run. It will not run on Insider Builds after 10240 due to updates as noted in the Known Issues section on MSDN. (See Other resources below.)

System requirements

Client: Windows 10 build 10240 exactly

Server: Not supported

Phone: Windows 10 build 10240 exactly

Build the sample

  1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
  2. Start Microsoft Visual Studio 2015 and select File > Open > Project/Solution.
  3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio 2015 Solution (.sln) file.
  4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

Deploying the sample

  • Select Build > Deploy Solution.

Deploying and running the sample

  • To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or select Debug > Start Without Debugging.
